Disc brake pad cushions

a disc brake pad and disc brake technology, applied in the field of disc brake pads, can solve the problems of large heat generation between disc brake pads and brake rotors during braking, adversely affecting mechanical and hydraulic systems, and affecting the performance of brake discs, so as to reduce excessive and uneven heat, reduce friction, and simple and cost-effective

Abstract

Cushions for disc brake pads are disposed between the brake pads and their caliper pistons or caliper fingers. The cushions possess such characteristics of resilience that, during braking action, brake pads follow irregularities and ride over high spots on rotor faces. This action significantly reduces uneven frictional drag, which lowers braking temperature increasing braking efficiency and brake system longevity. Each cushion comprises a resilient body which is further comprised of either a material, such as an elastomeric pad, or a structure such as a compressible spring or other apparatus.

Description

CROSS-REFERENCE TO RELATED APPLICATION

[0001] This is a continuation-in-part of co-pending U.S. patent application Ser. No. 11 / 166,569 filed Jun. 25, 2005.BACKGROUND OF THE INVENTION

[0002] Disc brake systems are well known, having been used extensively in the automotive industry. These systems are produced in a wide variety of sizes, types, and configurations, but the basic function of disc brakes is to convert kinetic energy, the energy of motion, into thermal energy, or heat. As designed, the friction between disc brake pads and brake rotors during braking generates large quantities of heat as brake systems convert kinetic energy into heat to slow or stop moving vehicles.

[0003] Nearly all disc brake systems are comprised of certain basic components. Among them is a caliper that surrounds at least a portion of a brake rotor. Mounted in the caliper are brake pads which are designed to press against the rotor causing the disc brake to slow the vehicle using the brake system. The pr...
